Patented Nov. 19, 1929 UNITED STATES PATENT OFFICE FRANK M. EDGAR AND THOMAS P. ARCHER, F DETROIT, MICHIGAN ASSIGNORS '10 TERNSTEDT MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORFORATION OF MICHIGAN HANDLE ASSEMBLY Application filed May 6, 1926. Serial No. 107,179.

This invention relates to handle assemblies, and has to do particularly with such assembliesadapted' for use in the operation and regulation of windows of automobiles. In handle assemblies of the character referred to, a hand crank'is' ordinarily provided, and this crank has a hub which extends through the wall of the automobile body, and which is operatively connected to the window regulator mechanism. In order to hold the crank ,in position, a bushing) is usually rotatably mounted upon the hu and this bushing is fixed to the wall of the automobile body or to a stationary part With such a construction it is desirable that the bushing and the hub be accurately fitted to insure proper rotative movement between the parts when the crank is turned, and at the same time the bushing must be securel fastened to the hub to prevent the crank om being pulled out of place. Also it is desirable that the hub and bushing be provided with accurate thrust bearings so that no binding occurs when the parts are assembled. I

. According to the invention, the hub and the bushing are constructed to providespaced bearings, which permit rotative movement '30 between the parts. The two parts are associated in such a way as ,to form a chamber between the two spaced bearings, and within this chamber an anti-rattle spring may be placedd The hub also presents a thrust bearmg surface against which one end of'the bushing abuts and both the bushing and the hub are constructed with shoulders which are spaced a predetermined distance from the thrust surface vof the hub. A ring is fitted against the two shoulders when the parts are put together, and the ring is then securely held in place, and it provides a thrust bearing in.opposition to the thrust bearing surface of'the' hub, and at the same time serves to hold the" arts together. The construction is such t at when the parts are assembled the thrust bearings are in. accurate adjustment and no binding of the parts occur.

This novel construction in which the bearing surfaces between the hub and the bushing are spaced apart, insures proper rotative movement and prevents swinging movement of the hub relative to the bushing when the crank is turned by an operator. The antirattle spring is completely housed, and the space which lies between the spaced bearings is utilized for this purpose. The construction also afi'ords thrust bearings between v Fig. 3 is a sectional view of.t he'.parts in disassembled relation.

Fig. 5 is a section taken on the line 5-5 of Fig. 2.

In these drawings a hand crank "1 of any desired construction is provided with a hub 2 projecting therefrom. This hub 2 is provided with a thrust bearing surface 3 and an offset portion providing a shoulder 4. Lying between the thrust bearin surface and the shoulder is a bearing sur ace 5. .A second offset portion provides a shoulder 6, and a bearing surface 7 lies between the shoulder 6 and the shoulder 4. The innermost end 8 of the hub, which is of reduced diameter, may

be beveled, as shown at 9. v

A bushing or rose 10 is adapted to fit over "the hub of the crank, and has one endprovided with a thrust bearing surface 11 which abuts against the thrust bearing surface 3 of the hub. The interior of, the bushing provides a bearing surface 12 which 'fits the hearing 5 of the hub when the bushing is in position. The interior of the bushing is provided with an annulus 13 which fits over the hearing surface 7 of the hub. The annulus 13 provides shoulders 14 and 15, and when the" parts are in assembled relation the shoulder 14 is spaced from the shoulder 4 of the hub,

' and the shoulder 15 isin alignment with the shoulder 6 of the hub.

In order to hold the parts together, a ring 20 is placed over the reduced end 8 of the hub i and within the inner end of the bushing.

This ring abuts against the aligned shoulders and 6, and the end of the hub is then turned outwardl 1 (preferably by spinning) as I shown in 'g. 2, over a 11310110 the mug and the parts are'securely ocked together.

Due to the fact-that the spacing between the shoulder 15 and the bearin surface 11 of washer may be of any desirable material 1 less, width :than the portion 12 of the bushing,

of suflicient strength to retain the parts to- I gether and to provide suitable thrust bearing surface. The bearing surface 5 of the hub which fits within-the portion -.12 of the bushing, is of and a chamber 21 is thus provided between theshoulder ,4 of the hub and the shoulder 14 of the bushing. Within this chamber an vanti-rattle sprm 22is inserted during the ,assemblin of t e. parts. Th anti-rattle 'sprin is t us completelyhoused and is positione between the bearing surfaces between the hub and the bushin As shownin the drawmgs, the bushing may be provided with external threads23 for the purpose of securing the same to a stationary part of the automobile body, or to a part of the window regulator mechanism, and the bushing ma be also providedwith a serrated end 24 whic assists in preventing rotation of the bushing after the same has been threaded to position. Also the hub of the housing is shown as having arecess 25, which recess may .be utilized for operatively connecting the hub to the regulator mechanism. I

- It will thus be seen that the invention pro vides a handle assembly wherein the bearings between the members are spaced and any. .swinging action which may result by reason of the operation of the handle is in a large measure prevented. Also the construction is such as to positively prevent the binding ac-. tion between the parts when the inner end of the hub is turned over and the thrust bearing adjustment is assured regardless of varying pressures which may be encountered in the turning operation.
